Journal of Minimum Intervention in Dentistry - Volume 8, Issue 4, January 2015

Search result: There is still a lack of studies to this topic and only two clinical studies concerning restorations in the primary dentition were found.

---

Clinical outcomes: The results of (conventional) high-viscosity GIC indicate no difference to amalgam while, low-viscosity GIC perform significantly worse than amalgam.

---

State of evidence and recommendations: The quality of the existing evidence requires further assessment.

['Preliminary Systematic Literature Searches' are based on SYSTEM's periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of databases searched, as well as the assessment of precision and internal validity of results and thus do not replace the need for a full systematic review report to the topic]

Search result: Ten controlled clinical studies relevant to the topic were found.

---

Clinical outcomes: The results indicate:

1. GIC/RM-GIC have higher caries-preventive effects than composite/amalgam in cases were no additional fluoride was provided to patients have been shown;
2. Topical fluoride is indicated as caries-preventive;
3. Mineral containing supplements, with and without casein appear to be at least as effective as topical fluoride in caries prevention;
4. The effect of chlorhexidine gel on caries prevention is unclear;
5. The use of an Intraoral fluoride-releasing system appears as effective s topical fluoride application.

State of evidence and recommendations: The quality of the existing evidence requires further assessment.

Search result: There is still a lack of studies to this topic and only two clinical studies concerning restorations were found.

Clinical outcomes: The results indicate no difference in the retention rate after 12 and 42 months in Class V and Class II restorations, respectively.

Search result: Two clinical studies were found.

---

Clinical outcomes: The results indicate a higher fluoride concentration in plaque surrounding teeth that were either bonded or restored with resin-modified GIC than with compomer.

Search result: Only one clinical study was found.

---

Clinical outcomes: The results indicate that GICs release more fluoride under clinical conditions than fluoride containing composite resin.

SYSTEM Initiative: Results from laboratory studies comparing high-viscosity glass-ionomer cement (HVGIC) with amalgam for tooth restorations do not share the same effect direction and magnitude of results from controlled clinical trials. Laboratory trial results may thus not correctly reflect clinical reality and should not be used for clinical guidance concerning HVGICs in daily dental practice.
